Heating hose system for co-extrusion in the plastics industry

H 800 Special250 °C

For very high temperatures and pressure loads.

The H 800 series heating hose systems combined with the T3 PTFE series pressure hose are very often used as connection hoses between a co-extruder and a tool. Rigid connections and a multitude of connection elements are eliminated, which would normally need to be individually heated, insulated and controlled. The flexible connection considerably simplifies tool changing and maintenance. The H 800 also compensates thermal expansion and vibrations. The heating system can be easily fitted in your installation
